In April 20, 2013, a strong earthquake measured Ms 7.0 hitted Lushan county, Sichuan province, which was induced by Longmenshan front fault, i.e. Dachuan-Shuangshi fault. It was the second large earthquake occurred along Longmenshan fault zone since Wenchuan earthquake in 2008. From April 25 on, the authors made three field visits to the quake-hit area. The disasters were summarized, and the potential problems during post-quake reconstruction were discussed. The results showed that compared with Wenchuan earthquake, the quake-induced disasters were lighter; no obvious surface ruptures were ever witnessed along the quake-inducing fault; both landslide and rockfall happened in small scale, so no large barrier lake was ever formed; landslide distributed along the seismogenic fault, and the rock types were Xujiahe Formation of Upper Triassic; rockfall appeared mainly in the gorge segment of rivers, and the rock types were mainly conglomerate and secondly intrusive rock; severe building damages were mainly brick-wood structured residential housings or brick-concrete-structured ones without constructional columns or ring beams; the major geohazard problems during post-quake reconstruction were rockfalls along major roads and debris flow in Baxing county town.
